Down on his luck after losing his job and his girlfriend on the same day, Larry decides to join his neighbor, Bill, and his combat-happy buddy, Everett, for a relaxing weekend of drinking and target practice. But when the three hapless guys are mistaken for Army Reservists, they're loaded onto an army plane headed for Fallujah, Iraq - and mistakenly ejected in a Humvee somewhere over Mexico. Convinced they're actually in the Middle East, the clueless wannabe soldiers lay down their beers and take up their arms to save a rural village - and prove they just might be heroes after all.
